Setup and Configuration

Post Installation

After installation, consult the User Guide for information on using the program. It is found in the 'measureJ2X\docs' directory of the installation, or by running the program (double click on the icon created during installation) by using the Help, User Guide menu item. This guide contains step-by-step instructions for some of the more common measuring scenarios and explanations of menu items. Please be sure to understand the File, Open and File, Save menu items and AutoSave, Append and Overwrite options before beginning measurement of important data.

A file called 'test.raw' is installed in the top-level directory. The data in this file can be read in using the File, Open menu item and used to explore many of the program features without requiring a measuring stage to be connected. The files 'ewlwTest.rwl', 'ewlwTest.ewl', 'ewlwTest.lwr' are also available for testing of earlywood/latewood features.

The MeasureJ2X documents which are found locally in the docs directory after installation are also available on-line at the ProjectJ2X web site.   The web site always contains the latest and greatest versions so please always check the web site for possible updates from your distribution:

If you are not already familiar with the licensing agreement for MeasureJ2X, please review the license terms found in the license file.  The licensing terms are part of  ProjectJ2X, under which the software was developed.
